3. Call the FSS's initialization function, passing in a table of seven
configuration parameters
4. Call a C-library function to install the FSS instance as the default

That is all! Our application's calls to the
the directory manipulation functions now apply to the EZ-KIT Lite hard
disk. The FSS automatically takes care of initializing and controlling the
physical device driver (for the disk) and the file system driver (for the FAT
file system).

The most interesting part of the configuration process is how the DMA
chains for the frame buffers are initialized, and how the DMA data flow is
set up. In
